Drain apparatus with branch tube and valve

ABSTRACT

The disclosed Drain Apparatus with Branch Tube and Valve is a cylindrical tube consisting of the outer tube ( 1 ) and inner tube ( 13 ). The bottom part of the outer tube ( 1 ) has 2 locks ( 4 ) ( 5 ) to prevent the movement when inserting the inner tube ( 13 ) into the outer tube ( 1 ). The upper part of the inner tube ( 13 ) has a hole ( 8 ) of similar size to the branch tube ( 2 ), branching from the outer tube ( 1 ), to allow high-pressure water or air flow through the inner tube ( 13 ). Above the hole ( 8 ), a valve ( 6 ) is mounted inside the inner tube ( 13 ). In its normal position, the valve ( 6 ) will perfectly close the end of the hole ( 8 ). When high-pressure water or air flows in, the valve ( 6 ) will be pushed upwards to close the upper opening. The water or air will flow along to push blockage and waste out of the drain.

BACKGROUND OF THE INVENTION

The previous Thai Patent application No. 071847 reveals the invention of drain apparatus with branch tube and valve to remove blockage in the drain. The cylindrical apparatus is made in two identical pieces to be attached to each other to form a tube. The material used is plastic. This has caused several defects as follows:

1. Rugged and uneven surface

2. Leak

3. Uneven connection point

4. Fragile

The present Invention acknowledged these defects and is consequently produced with improved characteristics to achieve greater and more efficient result.

This Invention is related to Civil Engineering

BRIEF SUMMARY OF THE INVENTION

The cylindrical body of the Drain Apparatus is composed of 2 parts, which are the outer tube and the inner tube. The outer tube is a manufactured in one piece with small tube branching on its side; while the inner tube is composed of 2 pieces attached to each other to form a tube with a valve affixed inside. The inner tube which is relatively smaller than the outer tube is to be inserted into the outer tube with a lock to prevent movement without use of glue or other means of connection.

The primary objective of this Invention is to remove blockage and waste in the drain, using the power of water pressure or air pressure. Moreover, this unique, simplified and effective Invention will help to increase convenience in life, save time, money and labor from the traditional blockage removing methods. More importantly, it helps protect the environment and dispose the waste properly with absolutely no use of chemical substance.

With use of this environment-friendly Invention, it is not required to disassemble the drain or use chemical substance to corrode the drain, causing severe damage to the environment.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1. is the outer tube (1) that is manufactured in one piece with small tube (2) branching on its side. Inside the outer tube (1), a seat (3) is positioned above the small branch tube (2) to prevent movement of the upper part of the inner tube. The bottom part of the outer tube also has 2 locks (4) (5) to prevent the movement when inserting the inner tube into the outer tube without necessary use of glue or other means of connection.

FIG. 2 is the inner tube (13). The inner tube is composed of 2 identical pieces attached to each other to form the cylindrical tube (13). The outer diameter of the inner tube (13) which is relatively smaller than the inside diameter of the outer tube (1) is to be inserted into the outer tube (1). The upper part of the inner tube has a hole (8) of similar size to the branch tube diameter (2) from FIG. 1 to let high-pressure water or air flow through the inner tube (13). To prevent movement when inserting the inner tube (13) into the outer tube (1), the bottom part of the inner tube (13) has 2 small buttons (11) (12) to be associated with the 2 locks (4) and (5) of the outer tube (1).

FIG. 3 shows the sectional view of the inner tube (13). Above the hole (8), a valve (6) is mounted inside the inner tube (13). In its normal position, the valve (6) will perfectly close the end of the hole (8), leaving its upper opening open so the sewage can flow downwards. Also, there is a valve seat (7) under the upper opening of the inner tube (13) for coupling with the valve (6) when high-pressure water or air pushes the valve (6) to move up to close the upper opening. Inside the inner tube (13), there is also the concave part (9) underneath the hole (8), and the convex part (10) is lower.

FIG. 4 is a sectional view of Drain Apparatus with Branch Tube and Valve when inner tube (13) is inserted into the outer tube (1). Inner tube (13) is completely pushed via the bottom opening of the outer tube (1) until the upper opening of the inner tube (13) reaches the seat (3) inside the outer tube (1). The hole (8) of the inner tube (13) will align with the hole of the branch tube (2) of the outer tube (1). When the high-pressure water or air is connected to the branch tube (2), the water or air will flow through the hole (8) and the inner tube (13). In its normal position, the valve (6) will perfectly close the end of the hole (8), opens it upper opening so the sewage can flow downward.

FIG. 5 is sectional view of Drain Apparatus with Branch Tube and Valve when the inner tube (13) is inserted into the outer tube (1). When the high-pressure water or air flows through the branch tube (2), the water or air will push the valve (6) upwards to close the upper opening by coupling with the valve seat (7).

Therefore, the water or air cannot flow upwards, but will flow downwards to remove blockage and waste in the drain.

FIG. 6 is a sectional view showing connection of drains at several points with this Drain Apparatus with Branch Tube and Valve. Starting at the branch tube (2), when the high-pressure water or air is connected, water or air will flow through the hole (8) and push the valve (6) into the position the closes the upper opening by coupling with the valve seat (7). The water or air will hit the convex part (14) of the second Drain Apparatus with Branch Tube and Valve and then flow into the concave part (15). Then, the pressure of water or air will push the valve (16) upwards into the position that closes the upper opening by coupling with the valve seat (17).

FIG. 7 is a continuation from FIG. 6. When the valve (16) closes the upper opening of the second Drain Apparatus with Branch Tube and Valve, the water or air will flow along tube 18 to push blockage and waste out of the drain.

FIG. 6 and FIG. 7 clearly show that the Invention has been improved to create more efficiency. With multiples connection of Drain Apparatus with Branch Tube and Valve and only one point of water/air pressure flow, blockage and waste at any position along the drain can be removed. The valve at the first position will be pushed by water/air pressure to close the outer tube's upper opening. The valve at other positions will also be pushed by flowing water/air to close the outer tube's upper opening according to the statement outline above. 

1. This detachable Drain Apparatus with Branch Tube and Valve to remove waste in the drain has the unique characteristic: it can be detached into 2 parts, which are the outer tube and inner tube.
 2. The one-pieced outer tube is of cylindrical shape consisting of the branch tube (2) branching from the upper part of the outer tube (1) to allow air or water to flow in and remove waste in the drain.
 3. Following claim No. 2, there are two locks (4) and (5) at the bottom part of the outer tube (1) to support the inner tube when inserted into the outer tube.
 4. The inner tube consists of 2 pieces. Each piece is identical. When assembled together, it forms a cylindrical inner tube (13) which is slightly smaller than the outer tube (1). It can be inserted into the outer tube (1).
 5. The inner tube (13), as claimed in claim No. 4, has a hole (8) to allow air or water inflow
 6. On the inner tube (13), as claimed in claim No. 4 or 5, there is a valve (6) affixed inside the inner tube (13) above the hole (8). In normal position, the valve (6) will close the hole (8)
 7. As claimed in claim No. 4,5 or 6, when the inner tube (13) is inserted into the outer tube (1), the hole (8) of the inner tube (13) will be in the same position as the branch tube (2) of the outer tube (1). When the valve (6) is open, air or water will flow through the branch tube (2) and the hole (8) into the inner tube (13). High pressure of air or water flow will push the valve (6) to couple with the valve seat (7) and close the upper opening. Air or water flow, blocked from going upwards, will then go downwards to remove waste or blockage in the drain.
 8. As claimed in claim No. 4,5 or 6, when the inner tube (13) is inserted into the outer tube (1), the small buttons (11) (12) of the inner tube (13) will couple with the locks (4)(5) of the inner tube (1) respectively. This will firmly lock the outer tube (1) to be attached with the inner tube (13).
